Wild Essentials home diffusers are the perfect solution to diffuse in any size room. Our 700ml diffuser uses AC power and is an aromatherapy/essential oil diffuser, humidifier, vaporizer, air freshener and multi colored (7) LED nightlight - all in one. Simply fill the water chamber with up to 700ml of water (about 3 cups) and a few drops of your favorite essential oil or fragrance for hours of use! Our home diffuser has a very quiet (under 25dB) operating cycle and uses 2.4 MHZ ultrasonic frequency technology. Our diffuser has an LED nightlight with 7 different colors in both bright and dim modes available so you can keep it on your favorite color or have them automatically change or have no light at all for overnight use. Can be used with or without fragrance/essential oils as a scent free humidifier or vaporizer. Comes with a 700ml diffuser, AC cable and instruction guide.
